In this paper, the electrical conductivity of the fabric reinforced filled stratified epoxy composites measured by two methods was investigated. This electrical parameter was measured by two-point and four-point (Van der Pauw) techniques. It was studied the electrical behavior of the epoxy composite materials reinforced with carbon, glass and aramid fabrics with the medial layer made of three different types of fibers (carbon, aramid and glass) and copper wire. In this investigation, also, it was analyzed the influence of the ply orientation and the fillers addition in the epoxy matrix composition. The test results showed that the fiber orientation led to an increase of the electrical conductivity of the carbon fabric reinforced plate and the fillers improved significantly this property of the hybrid fabric reinforced plate.
